Every now and then my wifi and cellular signal stop working. the phone doesnt recognize the sim card. Both stop working at the same time. Sometimes it takes one reboot to work again some times more. Some times the phone recognizes the sim card at random times and asks me for my pin after wifi and cellular network have stopped working for a while. Some times rebooting doesnt solve the problem immediately but it takes a minute or two for wifi and sim to work. I tried reinstalling miui through the update up and i did a factory reset but it didnt help. Im using the latest pie version on 3gb/32gb global version

My phone started turning on and off its 3g connection. Wifi works solid.
I'm on a good signal area. It's not like the 3g is on and I can't connect in anything.
The problem is that the phone turns on and off. It doesnt fix the 3g connection.
Also, Checkin service it's draining the battery a lot.
Looks like a software problem with Google Play Services and its Connection checking service.
Anybody have seen this problem?
thanks in advance.
Starting to worry right now. Did a factory reset on a flashed V10j KDZ and it didn't change.
TWRPed a 20A Lollipop rooted ZIP and it didn't change. Right now I'm trying to go back stock using LG PC Suite.
I can't understand why this can be a hardware problem because 3G actually works but it keeps constantly getting on/off in ~10 seconds intervals.
Looks like a bad system file that is messing with it.
EDIT: Also, the phone can't search for mobile networks anymore. I just tell it to do a manual search and it can't find anything.
What would this be? Modem file broke? WTH.

I have random disconnects/drops too, Although my 3G/LTE icon never actually goes away, just the signal.
Personally I would suspect your modem as #1 suspect.
Factory reset rarely fixes much, I would try re-flashing the phone.
If KDZ flash doesn't fix it maybe try a tot & dll flash using LG Flash Tools with modified megalock.
It definitely looks like a modem issue BUT it can be a your os. I had issues where my modem wouldn't flash from a stock flash on my S4, But manually flashing my modem would SOMETIMES work, I would have to flash the modem a few times usually before it would actually flash.
I had problems before but it was caused by network. Did you tried with different SIM card from other network?
I have the same problem and couldn´t fix yet... Didn´t try to use another SIM card to check if is a network trouble, but it´s driving me crazy to be without connection and a huge battery draining...
Any other ideas?

Just try with other network SIM. I had same problem long time back with Nokia n96, Motorola defy and some other phones. Some of time it helped to set phone only to use 2g network. That was happening the most of time when i used VIP network in Serbia.
Setting only 2g signal helped sometimes but after changing SIM card, problem was solved.
This problem happen to me without reason and after some time i tried same network again, there was no problems.
Probably a different SIM will correct the problem, because after a lot of trial and error changes I realized that the current Network APN (you can reach going on Mobile Networks inside Connections and Networks [translation] in the Settings) was faulty. I deleted the APNs and made a restore. (Delete and Restore are the only options inside Network APNs).
I imagine that changing SIM cards from another carrier will reconfigure the APNs and probably fix the problem.
I´ve tried a different SIM card and didn´t found any troubles, but when I put mine, the problem come back again... So it´s a problem with my carrier. I´ve deleted the APN settings, restart, restore, restart again and didn´t solve. I´ll call them to check if they are experiencing any network issues.
Hi, I have a problem with my device. Disclaimer: I'm very noob so please be patient.
I'm starting to get SIM CARD REMOVED error since i changed my network provider. My previous sim card was not LTE, just 3g and it had no problem with the device. The new sim card is LTE. It took me literally 5 days after enjoying the new network provider till my device acting weirdly.
Before changing, I upgraded to MM. Originally my device does not support LTE, but then I played with the system (sorry for bad terminologies) and make the feature available. No problem detected with old sim card.
So, I tried the old fashioned way; Hard Reset. I had the device reset twice but nothing changes. Frustrated of the constant automatic reboot, I wiped all system, delvik, cache, etc using TWRP. Then i installed CM13 and use it as my OS. It works well. I got the signal with LTE data. Realizing that the ROM does not come along with Google Play Store, i installed gapps. Soon after restarting the phone, the signal only lasts for an hour then it says " NO DATA SIM". I figured a temporary solution which is, rebooting the device after you lost the signal. It is just temporary though. The signal will once again lost.
What I have tried: 1) Locking the simcard while the phone still got its signal.
2) Changing values using this guide-> http://forum.xda-developers.com/lg-g3/help/annoying-lg-g3-problem-lte-signal-solved-t3293721
* My sim reader does not seem to be having any defect.
Any help would be greatly appreciated! Thanks!
Got this phone from a friend and immediately flashed the last CM 14 Rom before they shut down. Flashed the experimental Lineage Rom then started the Nightlies. It's on the most recent Nightly now. The issue I'm having involves the SIM card, and now bluetooth (though that only happened once). I can't get it to connect to the network. It was an AT&T phone originally, and yesterday I finally got it unlocked to use on T-Mobile. The card is registering, I see the triangle in the status bar, but none of the solutions I've found can make it connect (the card works in another phone). When trying to connect to the network it eventually just times out. I can't even add APN settings as they won't save. This morning it forgot previous bluetooth connections as soon as I clicked on them. I'm thinking I need to flash an older radio.img but I can't find anything that isn't almost 3 years old. In addition, I can't keep the SIM unlocked. It asks for the SIM unlock PIN every time the phone boots, and the Security setting option is grayed out so I can't even turn it off. Any ideas? Is this all related to being S-on? Based on what I've read, I was under the impression that didn't matter anymore.
I am using Z2 plus from about 15 months with Jio sim with VOLTE enabled without any issues. Suddenly VOLTE has stopped working. Toggled VOLTE, toggled data/airplane mode, tried multiple restarts but VOLTE is not working. Data (internet) is working w/o any issue but I can't make/receive calls as VOLTE is not working. Appreciate if somebody can offer any solutions.
Im also facing the same issue from today(15/8/2018 IND Independence day).
I flashed tons of ROMs and still the problem persists.
Please find a FIX for this.
It has happened many times to me. Try these steps :
1. Eject the SIM tray
2. Interchange the SIMs
3. Let the network bars appear.
4. Turn off the phone
5. Interchange the SIMs again
6. Start the phone
It works :fingers-crossed:

Thanks madhurjajoo but this doesn't work for me. I also suggest that you try toggling airplane mode on/off next time you face the issue. So far that's solution that worked for me when VOLTE stops working but nothing working this time.

I have faced this problem for a lot of time. In the end, i installed stock rom again via mi flash tool - Zui v2.5 (you will easily get the link in xda). Once i got HD symbol and tested a call, i clean wiped the phone and installed custom rom again which supported volte. But before starting the rom for first time, i flashed baseband v1.7 (which i think is of zui 3.5). I got volte after 5-6 months and I'm happy.... My current rom AospExtended Oreo based doesn't have great battery backup but atleast I'm content with VoLTE. Hope it helps
Hello
I have just received yesterday a Note10+ and everythings work fine.
Howover since this morning the cell network just constanly reset (status switch between Disabled network and No Signal)
The phone also asking for sim card pin everytime. (Most of time for the 2nd time but ask some time for the 1st also)
Question : does a full odin wipe with Efs clear can help ?
Thank you
Have you checked the sim card?
Yes phone has 2 sim card from 2 provider tryed swapping, one sim card nothing worked
I finally ended with full wipe with odin and fixed the problem but i guess the background problem is still here since i can see randomly the signal bar going complety disconnected (crossed circle) before going back a few second after
I guess there is a software issue in Samsung rom since odin fix the issue
